This invention relates to operating core sections for a brake on swivelling wheel sod is illustrated as embodied in an opera);- mg connection for an automobile front wheel brelze. An objece of the invention is v to gyoroclime so inexperisive control. for a brass on such a swivelled wheel, eliminating mostof, the earts going; to make up the usual universal joints, else, by 115L115 so brokeapplyiog she-fia member formed of heli- Preferably each helix used as s, brekc-aioplyisg is closely Wound E'rom a Strip rec'zosguler in orosscation,x thus giving is maximum torsionsl strength, especially where is rocked shoot axis in a. direcsion which tightens the coils.- The helix may, if (lesire l be clirectly connected to the brake-actuating means at its outer end, swivelling l the wheel, sncl is suitably supported at its inner end, as, :lor example by a bracket carried by time chassis frame,

Elie figure is a vertical section slirougli automobile fiont wheel brake sod through associated pores of the ve" i68 showing the control for the brake partly vertical section and poxtly in rear elevation.

In the arrangement select-ed for illustration, the brake includes a drum l0 rotating with the Wheel (not shown) rotatably mountedon e knuckle 12 swivelling by means of the usual king-pin i l at one end of thefront axle 16, which, with s rear axle which is not shown, supports by the ususl springs 18 a chassis frame 20. The brake is illustrated as including slices 22 applied by means shown as s double cam 2e mounted on a short cam shaft 26. The above-identifiecl ports or their equivalents may be oil any (lesirecl construction.

According to the presenl invention the brake is applied by a horizontal shaft 28 shown as Wound. in the form of a helix, or co-am'el helices, from a strip which is rectangulerr in cross-section, so that the shaft has the maximum torsional strength. The single helix; shown is connected to the cam Serial Ho. $3,551.
